Plain and simple... to change i.e.

C#

var doc = XDocument.Load([FILENAME]);
doc.Root["Body"]["Monday"]["FiveToNine"] = "What ever";

to add

C#

var myNewElement = new XElement("NodeName", "NodeValue");
doc.Root["Body"]["Monday"].Add(myNewElement);

and save it afterwards...

Maybe you want to take a look at these pages[^]

---------------------------
Sorry, mixed up XmlDocument and XDocument....

C#

static void Main(string[] args) 
{

    var doc = new XmlDocument();

    doc.Load(@"MyFile.xml");

    //To change
    Console.WriteLine(doc["MediaPlayer"]["Body"]["Name"].InnerText);
    
    doc["MediaPlayer"]["Body"]["Name"].InnerText = "Something else";

    Console.WriteLine(doc["MediaPlayer"]["Body"]["Name"].InnerText);

    //To add
    var newNode = doc.CreateElement("Wednesday");
    doc["MediaPlayer"]["Body"].AppendChild(newNode);

    Console.WriteLine(doc["MediaPlayer"]["Body"].InnerXml);

    Console.WriteLine("Done...");
    Console.ReadLine();

}
